This Nixie shield was designed by Tyler around 2013, as an open source project. A little after the successful kickstarter campaign, it just disappeared. I was one of the backers and I received a couple of PCBs for my contribution. I used them to built clocks and I even wrote some review blog posts. I also re-designed the PCB from a simplified schematic (so this is a little bit different than the original).

This is the smallest Arduino Nixie shield out there that has 6 Nixie tubes on the same board (together with the high voltage supply and the tube drivers). With all components through-hole, it is relatively easy to assemble, although it requires a lot of soldering.

The 6 IN-17 Nixie tubes are not included in the kit, but they can be sourced on ebay or tindie/etsy.

Updated documentation can be found here.

Nick built his own clock and documented it here.
